To explore the regulation of long-chain noncoding BANCR on cell invasion and migration of esophageal squamous carcinoma cells and related mechanisms.
The mRNA expression of BANCR in esophageal squamous carcinoma cells and esophageal squamous cells was detected by quantitative PCR . The relationship between the expression of BANCR and the survival rate of patients with esophageal squamous cell carcinoma (ESCC) was analyzed by Kaplan-Meier method. The BANCR pair was detected by Transwell invasion and scratch test. In ESCC cell lines, the cells had invasion and migration ability; Western blot was applied to detect the expression of proteins involved in the Wnt/β-catenin signaling pathway.
BANCR revealed relatively high expression in esophageal squamous carcinoma cells, and the higher the expression of BANCR was, the lower the survival rate of patients with ESCC was. Inhibition of BANCR expression could effectively reduce the invasion and migration ability of esophageal squamous cell carcinoma. After silencing BANCR, the expression of wnt3a, survivin, β-catenin and c-myc protein was downregulated compared with the negative control group (p<0.05).
Long-chain noncoding BANCR was highly expressed in patients with ESCC and was negatively correlated with patients' survival time. It was of the capability to modulate the cell migration and invasion of ESCC cells through inducing Wnt/β-catenin signaling pathway.
探讨长链非编码RNA BANCR对食管鳞状癌细胞侵袭和迁移的调控作用及其相关机制。
采用定量PCR检测食管鳞状癌细胞和食管鳞状上皮细胞中BANCR的mRNA表达。采用Kaplan-Meier法分析BANCR表达与食管鳞状细胞癌(ESCC)患者生存率的关系。通过Transwell侵袭实验和划痕实验检测BANCR对细胞侵袭和迁移能力的影响。在ESCC细胞系中,细胞具有侵袭和迁移能力;采用蛋白质印迹法检测Wnt/β-连环蛋白信号通路相关蛋白的表达。
BANCR在食管鳞状癌细胞中呈相对高表达,且BANCR表达越高,ESCC患者的生存率越低。抑制BANCR表达可有效降低食管鳞状癌细胞的侵袭和迁移能力。沉默BANCR后,与阴性对照组相比,wnt3a、survivin、β-连环蛋白和c-myc蛋白的表达下调(p<0.05)。
长链非编码RNA BANCR在ESCC患者中高表达,与患者生存时间呈负相关。它能够通过诱导Wnt/β-连环蛋白信号通路调节ESCC细胞的迁移和侵袭。
